Examples

# converting sparse matrix
mat <- Matrix::rsparsematrix(nrow = 10, ncol = 10, density = 0.1)
rownames(x = mat) <- paste0("feature_", 1:10)
colnames(x = mat) <- paste0("cell_", 1:10)
g <- as.Graph(x = mat)

# converting dense matrix
mat <- matrix(data = 1:16, nrow = 4)
rownames(x = mat) <- paste0("feature_", 1:4)
colnames(x = mat) <- paste0("cell_", 1:4)
g <- as.Graph(x = mat)
